An exposure simulation study was conducted to characterize potential formaldehyde exposures of salon workers and clients during keratin hair smoothing treatments. Four different hair treatment brands (Brazilian Blowout, Coppola, Global Keratin, and La Brasiliana) were applied to separate human hair wigs mounted on mannequin heads. Short-term (6–16 min) and long-term (41–371 min) personal and area samples (at distances of 0.5 to 3.0 m from the source) were collected during each treatment for the… 
Case Study
M any hairstylists use hair straightening products that may potentially expose them and their clients to formaldehyde. One popular hair straightening product, Brazilian Blowout Acai Professional
Hairdressers are exposed to high concentrations of formaldehyde during the hair straightening procedure
The present study showed that hairdressers are chronically exposed to high concentrations of formaldehyde in the workplace and these exposures are mainly associated with the work process, where many variables of this process influence the intensity of exposure.
Hair straightening products and the risk of occupational formaldehyde exposure in hairstylists
Occupational exposures to hair straightening products in the studied hairstylist were found to expose them to formaldehyde concentrations that exceeded the standard limits.
Environmental and biological monitoring of occupational formaldehyde exposure resulting from the use of products for hair straightening
Comparison of the beauty salon workers from each of the six beauty salons revealed significant differences in urinary formic acid (FA) concentration before exposure, urinary FA after exposure, and variation in FA concentration before and after exposure.
Awareness, prevalence of hair smoothing products that contain formaldehyde and determinants of their harmful effects among women in Saudi Arabia
Assessment of keratin hair treatment among women in Saudi Arabia finds that Argan e Ojon was one of the most famous product tested with formaldehyde levels above 0.2% threshold, but it is worrying that it does not comply with GSO 1943 and SASO 1953 standards.
Indoor air quality in hairdressing salons in Taipei
The number of perming treatments, the number of workers, and the frequency of using formaldehyde releasing products, were found to be associated with the levels of formaldehyde, indicating that efforts are needed to improve the indoor air quality in hairdressing salons in Taipei.
Formaldehyde Exposure and Its Potential Health Risk in Some Beauty Salons in Kumasi Metropolis
Hairdressers in salons that provide the entire range of salon services captured in the study are at higher risk to the effects of formaldehyde, and about 50% of the salons had hazard quotient (HQ) above the safety limit and may, therefore, pose health risks to cosmetologists in these salons.
Asthma from hair straightening treatment containing formaldehyde: Two cases and a review of the literature
The results indicated that both subjects developed asthma from repeated occupational exposure to formaldehyde during hair treatments, and both subjects became unable to tolerate hair straightening activity in their vicinity.


Assessment of occupational genotoxic risk among Brazilian hairdressers.
The observed DNA damage could be associated with the hairdressers' occupational environment, where different chemicals are chronically manipulated and inhaled.
The Use of Multizone Models to Estimate an Airborne Chemical Contaminant Generation and Decay Profile: Occupational Exposures of Hairdressers to Vinyl Chloride in Hairspray During the 1960s and 1970s
Estimated lifetime doses for occupational exposures of hairdressers to VC-containing hairspray in hair salons were all below the threshold dose for HAS of about 300 to 500 ppm-years reported in the published epidemiology literature.
Residential Indoor Air Quality Guidelines
Indoor air quality (IAQ) is of prime importance to human health because we spend >80% of our time indoors. Occupants of indoor environments may be exposed to a variety of pollutants originating from

Mutagenic risks induced by homemade hair straightening creams with high formaldehyde content
The data show a more intense genotoxic response than those reported before for formaldehyde, suggesting that this compound may be acting synergistically with any unknown components in the creams or perhaps these unspecified components by themselves might have significant genot toxic potential.
A recommended occupational exposure limit for formaldehyde based on irritation.
The panel could not identify a group of persons who were hypersensitive, nor was there evidence that anyone could be sensitized (develop an allergy) following inhalation exposure to formaldehyde, but it concluded that if concentrations of formaldehyde are kept below 0.1 ppm in the indoor environment this should prevent irritation in virtually all persons.
